I took the habit of feeding fake random information to all websites asking too noisey questions and keeping track of them in case I need them for recovery. A website doesn't need my exact date of birth, at most it may need my approximate age. It doesn't need my real name either, even if it wants to deliver something to me, the address should be all it takes. It doesn't need my real email address, all it needs is some email alias that I can delete. Good practice for privacy, spam management and security since it is harder to guess this information and to reuse it when leaked.
